Applications
Sample positioning under high-NA objectives
Place and hold a specimen within the depth of focus while a long acquisition runs.
Optical path length adjustment
Trim delay lines, cavity spacing and interferometer arms with nanometre resolution.
Automated alignment axes
Serve as a driven axis in a rig where an operator would otherwise adjust a micrometer by hand.
Specifying this part
What this model has to survive, and what it needs around it
Speed derates sharply in vacuum
Rated at roughly 20 mm/s in air and around a tenth of that in vacuum, because a stick-slip drive depends on friction at the contact and on conducting the heat away. Size the axis on the vacuum figure if it will run in a chamber.
Encoder grade is a separate choice
Optical encoder at 2 nm on the standard grade and 0.5 nm on the .adv advanced grade. The mechanics are the same — you are buying the sensor, so take the advanced grade only if the measurement resolves below 2 nm.
Vacuum and non-magnetic versions
Most of the range is orderable as .HV (high vacuum), .UHV (ultra-high vacuum) or .NM (non-magnetic). The suffix changes materials, cabling and bake compatibility rather than the mechanics, so specify it against the chamber the stage will live in.
Full series comparison, controller pairing and mounting hardware on the ambient piezo stages overview, or work through the selection with the configurator.
